Stand-alone Operation
Stand-alone Operation Precautions
Do not connect the electric appliances listed below to the stand-alone outlets.
The amount of electric power generated during stand-alone operation
varies according to weather and storage battery charge. The inverter
stops stand-alone operation if it generates less electric power than that
consumed by the electric appliances connected to its stand-alone
outlets. Do not use the appliances listed below with the inverter, as
personal injury or property damage may occur if the power shuts off.
• Any kind of medical or home security equipment.
PROHIBITED • Desktop computers and other information-related equipment and
peripherals.
• Rice cookers, microwave ovens, and other cooking equipment.
• Heaters that use kerosene or gas.
• Other equipment that may cause personal injury or property damage
if the power shuts off.
•Confirm the backup panel, related wiring, and electrical fixtures
are in good safe condition before commencing stand-alone
operation.
MANDATORY
•If strange odors or noises are detected after starting
stand-alone operation, promptly stop stand-alone operation.
• Use the stand-alone outlets.
During stand-alone operation, power is supplied only to the stand-alone outlets. During a power outage, other outlets cannot be used.
• Stand-alone operation is automatically engaged if a power outage occurs.
• When power is supplied to electric appliances connected to the stand-alone outlets, inrush current may trip
protective devices and prevent the appliances from running.
The backup power provided by the inverter is envisioned to supply electricity to run refrigerators, TVs, lighting fixtures, laptop
computers and cellphones. Many lighting fixtures and refrigerators have protective circuits that trip and prevent the product from
running in case there is a surge in current when the power is turned on. Do not connect air conditioners, washing machines, and
other appliances to stand-alone outlets that may draw a large current when turned on.
• There is a limit to the amount of power that can be drawn at one time.
The maximum amount of current that can be drawn during stand-alone operation is 16.6 A. Only connect electric appliances
that consume less than 16.6 A. Though this will vary by appliance, a maximum of 16.6 A at 120V AC equates to somewhere
between 1.5 - 2.0 kVA. Moreover, 0.1 - 0.3 kW are needed to keep the inverter running.
If the electric appliances connected to the stand-alone outlets consume more power than is generated by the PV system and
supplied by the storage batteries, stand-alone operation shuts down.
Many lighting fixtures and motor-driven appliances (e.g., vacuum cleaners. refrigerators, dryers, etc.) draw a large current when
turned on, and consequently will not run. Using these appliances may also trip protective circuits and keep them from running.
• Electric appliances running off stand-alone operation may shut off.
Power output from the PV system and storage batteries can be unstable due to weather conditions and charge. If output
drops, stand-alone operation stops automatically.
• If stand-alone operation automatically stops due to high power consumption, the electric appliances that were
running stop temporarily. Although stand-alone operation resumes automatically when power consumption decreases,
connected appliances that have protective circuits are prevented from resuming operation.
